ATTACHMENT FOR MEAT-CUTTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 648,480, dated May 1, 1900.

Application led April l2, 1899.

T all whom, it' may concern:

Be it known that I, LOUIS BALLBAOH, a citi- Zen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Attachments for Meat- Cutting Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention is designed to form an attachment to the well-known form of meatcutting machine described in United States Letters Patent No. 339,834 and others of like character; and the object of the invention is to adapt said machine for mixing articles of food after they have been chopped.

To this end the invention consists in a simple attachment adapted to be combined with the casing and feed-screw of said meat-cutter and thereby convert the same into an efficient mixing-machine which not only serves the immediate purpose of mixing the meat after it has been chopped by the machine, but serves a variety of other uses in mixing articles of food, as in making mince-meats, eroquettes, &c., thereby greatly facilitating the work of the cook and promoting economy in housekeeping.

In the drawings, Figure l shows my attachment as arranged in operative connection with the meat-cutter. Fig. 2 is an end elevation of the attachment. Fig. 3 is a detached perspective view of the casing of the attachment. Fig. 4 is a perspective view of the mixing-cylinder detached, and Fig. 5 is a vertical section therethrough.

The dotted lines in Fig. l of the drawings represent that portion of the meat-cutter with which my attachment combines and which is composed of the casing A, the hopper B, the feed-screw C, journaled in the bearing E and provided withy the handle F, and the journalbearing at the rear end of the feed-screw, hav-- ing a squared portion D'.

My attachment comprises an open-ended cylindrical casing G, which has at its front end an interior screw-thread a, adapted to engage with the exterior screw-thread with which the end of the casing A is provided, and a set-screw b on the casing G is adapted to secure it against accidental unscrewing. In-

teriorly the casing G is provided with a num- Serial No. 712,737. (No model.)

ber `of radial spurs H, and at its rear end it has an exterior scre\ r-thread.c. Inclcsed in this casing is a cylinder K, closed at the ends and provided with radial spurs L, adapted to project into the intervals between the spurs H of the casing G. This cylinder has axially secured therein a tube M, in one end of which is fixedly secured the stub-shaft N, while in the other end is formed a square socket O,

adapted to receive the journal D' of the feedscrew C. Upon the stub-shaft N is journaled a cross-bar R, which carries the interiorly-screw-threaded ring S, adapted to screw on the end of lthe cylinder G. The stub-shaft N has a nut T at the end to hold the cross-bar R from slipping o.

In practice before applying my attachment to a meat-cutter of the kind referred to the latter is first put into the condition shown in Fig. 1, (by removing a perforated cap from the end of the casing A.)

When the attachment is properly secured, as shown, it will be seen that the squared portion D of the feed-screw engages into the socket O of the cylinder K, and the latter is held in engagement therewith by the crossbar R, in which the shaftN is journaled. The feed-screw C and cylinder Gare thus revolvedl together by turning the handle F, and by feeding the material to be mixed into the hopper B the feed-screw C willV carry the material into the cylinder G, where it will be thoroughly mixed by the action of the spurs L, which revolve in the interstices between the fixed spurs H. By the pressure of the feed-screw the material will be gradually expelled after being mixed; but by feeding the material faster or slower the operator has it entirely in his control how long the material shall remain in the mixing-cylinder, By feeding only at .intervals 4"the operator can mix each portion any desired length of time, and when he does want it to be discharged he feedsin fresh material, or, if the work is completed, he may remove theremaining portion by tilting the apparatus, so that the cylinder G is inclined -toward'the discharge end.

My attachment gives additional value to the meat-cutter not only for thoroughly mixing meat after it is chopped, but for adapting it to a variety of afteruses in culinary work.

My present construction diiers in several l and'support the same, a stub-shaft at the opthe removalof the cylinder K by unscrewing the ring S makes all the parts accessible for cleaning. My present construction also has the advantage that the cylinder G is open at both ends, which makes it easy to clean'.

A further advantage is the prolonged stub- `shaft N, which serves as a most convenient handle and support in manipulating the parts, in attaching them to the meat-cutter, and making the screwing of the cylinderG onto the casing and of the ring S onto the cylinderl G much more easy to accomplish than in my' former construction. 1

What I claim as my invention isfl'. A mixing attachment for meat-cutters,

vcomprising thev cylindrical casing G, having inwardly-projecting arms H, means for securing the casing to the meat-cutter, the cylin- Vstices between the arms H of the casing means at one end of said cylinder to detachably con-- nect it to the feed-screw of the meat-cutter ing the casing to the meat-cutter, the cylinder K adapted to revolve Within said casing and having arms L projecting into the intersticos between the arms II of the casing, a socket in one end of said cylinder to receive a projection on the feed-screw of the meatcutter and support the same, a stub-shaft N at' the other end of said cylinder and a ring S detachably secured to the casing G and having a central guide-bearing for thestub-shaft,

said stub-shaft extending rearwardly through said bearing and having endwise movement therein and the nutT.

In testimony whereof I affix my signature in presence of two witnesses. LOUIS BALLBAOH.
